## Problem summary
As AVX512 is available in most modern processors, it is good to use them if
have performance boost.
In latest bitshuffle, AVX512 have been added. We could make it integrated in
doris for AVX512 case.
Tested with master branch, queries can be boost from 1.4%~3.2%. use
run-ssb-queries.sh 5 times, each time with 100 iterations.
(SSB query q1.1.sql~q4.3.sql total 13 queries)
